27 HTM Official Solve by Teemu Tiinanen @ Finnish Open 2010

Scramble: L B2 D2 F2 L U2 L’ R F2 D’ L2 R D’ U R2 B2 R B D R F’
Solution: R2 U2 L’ D’ F’ B2 U’ B’ D2 B U B’ D B2 F’ U2 R U’ R’ U2 F2 R U’ R’ F U’ D (27 HTM)

Explanation:
Pre-move D

2x2x3: R2 U2 L’ D’ F’ B. D’ B2

Now I switched to the inverse scramble (pre-moves B2 D B’ F D L U2 R2)

Pseudo-F2L minus slot: D’ U F’ R U R’ F2
Leave 3 corners: U2 R U R’ U2 F

Insert B U’ B’ D2 B U B’ D2 at the dot to cancel 3 moves.
